Meh, I don't find 10 dollars to be all that much, looks like a quality game to me, just because it's using an older engine does not necessarily make it a worse game.
Seems to be a game where a lot of time and effort has gone into it.

I encountered a huge problem with the demo right from the start: clicking on Controls under the options menu crashes the game.

The demo seems playable enough, but I wasn't able to get very far in the first level after going through the portal because the timed door sequences are very unforgiving. I barely made it past the first timed door only to keep falling into the lava pit trying to hit the second button and promptly quit out of frustration.

My biggest problem with the demo is that it's simply too hard. Why was saving disabled? I've probably died nearly 50 times trying to beat the first level. I either fall into one of the many death pits or get killed by one of the monsters. This is on medium, and I'm not sure playing on easy would solve the problem.
